# useField

<PageDescription>{docs.exports.useField.description}</PageDescription>

## Introduction

The `useField` hook associates a form control with a label, and an optional description and/or error message. This is useful for providing context about how users should fill in a field, or a validation message. `useField` takes care of creating ids for each element and associating them with the correct ARIA attributes (`aria-labelledby` and `aria-describedby`).

By default, `useField` assumes that the label is a native HTML `<label>` element. However, if you are labeling a non-native form element, be sure to use an element other than a `<label>` and set the `labelElementType` prop appropriately.

**Note**: Many other React Aria hooks such as [useTextField](TextField/useTextField.html), [useSelect](Select/useSelect.html), and [useComboBox](ComboBox/useComboBox.html) already include support for description and error message elements. If you're using one of those hooks, there's no need to use `useField`.

## Example

```tsx render
'use client';
import {useField} from 'react-aria';

function ContactPicker(props) {
  let {labelProps, fieldProps, descriptionProps, errorMessageProps} = useField(props);

  return (
    <div style={{display: 'flex', flexDirection: 'column', width: 200, marginBottom: 20}}>
      <label {...labelProps}>{props.label}</label>
      <select {...fieldProps}>
        <option>Email</option>
        <option>Phone</option>
        <option>Fax</option>
        <option>Carrier pigeon</option>
      </select>
      {props.description &&
        <div {...descriptionProps} style={{fontSize: 12}}>{props.description}</div>
      }
      {props.errorMessage &&
        <div {...errorMessageProps} style={{color: 'red', fontSize: 12}}>{props.errorMessage}</div>
      }
    </div>
  );
}

<>
  <ContactPicker
    label="Preferred contact method"
    description="Select the best way to contact you about issues with your account." />
  <ContactPicker
    label="Preferred contact method"
    errorMessage="Select a contact method." />
</>
```
